Scheduling of a process chain in two meta process chains

Hi,

( Meta process chains - X, Z

X - runs at 2 a.m. daily

Z - runs after every two hours daily from 9 a.m. to 10.30 p.m

Process chain - Y is to be included in X & Z)

There is a Meta process chain X which is scheduled for 2 a.m. daily. This meta process chain contains another

process chain Y.

I want to schedule another Meta process chain Z which executes after every two hours daily. Now I want to include process chain Y in Z, with the condition that if system time is 11 a.m. or later than it only then it should be scheduled.

Since this process chain is contained in Meta process chain X, its start variant

has Immediate Start selected. I don't want to change this start variant.

Is there any option or event through which this can be achieved?

Thanks & Regards,

Manisha
